My invention relates to heat exchange devices and has to do moreparticularly with devices which are particularly adapted to closure suchas a room, or the like, with a.

minimum of friction.

Another object is to provide such a device which may be built up of a.plurality of simi-` lar units to any desired size depending'uponI theheat requirements of a given situation, and to construct the device sothat heating of the room is accomplished by connection and directcontact with the device. f

Many other objects and advantages of the kind described will be obviousto those skilled in the art from the disclosure herein given. To thisend my invention consists in the novel construction, arrangement andcombination of parts herein shown and described, and more particularlypointed out in the claims. v

Fig. 10 is a section taken on line '10 10 of Fig. 8. Referring lirst tothe embodiment shown .in Figs. 1 to 4, inclusive,I have shown a heatingdevice indicated generally at 10 in Fig. l mounted in a recess 12 formedin a wall 13 of a room and disposed under a window 15. Obviously, theheating' device 10 may be disposed in various other arrangements in thelcilic arrangement.

The heating device 10 comprises a plurality of similar units 16, ofwhich three are shown, although it will be readily apparent that anysuitable number of units 16 may be mounted in a given installationdepending upon the particular heat requirements. Each of the units 16comprises a hollow leg portion 18 having a front wall 19 and a rear wall19 and normally disposed with its longitudinal axis in a substantiallyvertical plane as shown in`Fig. 2, the leg being in communication with ahollow foot member 20. The foot members 20 comprise a plurality oflaterally projecting box-like members 22, having spaces 23 therebetween.Arranged in the spaces 23 between the members 22 are corrugated members25. These members 25 may be formed of any suitable heat conductingmaterial, such as sheet iron, galvanized iron or the like, and are sobent and arranged as to extend substantially the entire distance wall,and I am not to be limited to any spebetween the members 22 so as tomake a good contact therewith at each bend 26 Aand are of sulicientdepth to extend substantially from top to bottom thereof. J

A conduit 27 is provided for the inlet to the device 10 of heat exchangefluid which fluid is preferably steam although 'hot water may be used,if desired. The conduit 27 comv may be threaded through spiders 36formed in the cylindrical portion for retaining the units in fixedrelation. At the opposite end of the leg members 18 andv communicatingtherewith, are cylindrical portions 38 which are somewhat depressed fromthe level of the foot members 20 .so as to serve as drains therefor.Rods 40`extend through the cylindrical portion 38 and are in threadedengagement with spiders 42 formed therein. A plurality of push nipples44 is provided for effecting fluid tight connections between the variousmembers 16, these push nipples being seated in the ends of thecylindrical portions 33 and 38.

When devices embodying my invention are mounted in a recess of a wall,as shown in Fig. 1, a space 45 is preferably provided at the bottomthereof, and another space`46 at the top thereof. When steam is used asthe `heat exchange iiuid it is preferably introduced through the conduit27, the condensate draining into the tubular members 38 and passing outof the heating unit through the conduit 30. Obviously, if hot water isused as the heat exchange fluid, it may be intro`I duced through eitherone of the conduits.

When the device has been heated by means of any suitable fluid, air willbe induced Vto flow'into the recess 12 of the wall through the space 45and upwardly through the foot member 20. In 'passing through the spaces23 between the box-like members 22 of the foot member, the air will bedivided into a plurality of columns by means of the corrugated members25. Inasmuch as the members 25 are of heat conducting material and arein effective contact with the member 22 at a plurality of points 26,they will thus be maintained at substantially the same temperature asthe members 22 and hence the air will be very effectivelyA warmed byContact with the walls of the members 25 as well as.

by the members 22. After passing through the foot like members 20 theair will iiow upwardly through the recess 12 and will pass in P 'stoodthat the ends of the sheet of which contact withthe surface of the rearwall 19 18, thus effecting a further The air will then flow 46 and outinto the room. to the embodiments of a heat exof the leg members heatexchange. through the spa/ce Referring now Figs. 5 to 7, there is shownhere Y change unit indicated generally at and arranged/in a recess 71 ina wa 172 substantially in the same manner as in the other embodiments.The unit 70 comprises a tank 73 having walls 74 and 74 arranged insubstantially a vertical plane and communicating with conduits 7 5 and76 which may be used as an inlet and outlet respectively for heatexchange fluid. Adjacent the lower portion 'of the tank 73, so as toextend laterally therefrom and communicating therewith is apluralityoftubes 78, formed of heat conducting material such as metal.As best shown in- Fig. 7, these tubes are preferably U-shaped, the legsof the s being relatively short and the web of the Us being relativelylong. Obviously, this shape is preferred merely for the purpose ofeconomy of space and any other suitable configuration may be adopted,'if desired. The tubes 78, as shown in Fig. 7 are arrangedconcentrically and may also be arranged in arallel relation, as shown inFig. 6. Thus, in the particular embodiment shown, nine tubes 78 areutilized. However, it will be readily apparent that any convenientnumber may be used, and furthermore the tubes 78 may be disposed invarious other arrangements with reference to each other, and theparticular arrangement shown is to be considered as only exemplary.

A plurality of heat conducting vanes or fins 80 of heat conductingmaterial is provided on the tubes 78 andthese fins may be secured bysoldering, welding, or the like.

When a heat exchange fluid is introduced into the unit 70, a current ofair will be induced to enter the recess 71 through the space below thetank 73 and to flow upwardly past the tubes 78. The air will makeeffective heat exchanging contact with the tubes 78 and with the fins 80and will then low upwardly through the recess 71 and in y corrugations83 which will increase'the heating surface presented by this portion ofthe device and allow for contraction and expansion. This leg member isformed of a sheet of material bent upon itself having its front faceconstructed as just referred to and is rovided with a rear wall 84, itbeing underthis portion is formed are braced or otherwise securedtogether to form front andrear walls ofthe chamber 85. A As clearlyshown in Fig. 10, the chamberfis completed through the agency ofthe endwalls 86-86. A fluid supply pipe 87 is connected with the upper end ofthe chamber and a drain connection 88 is provided which connects with aU- shaped hollow element-89, the opposite ends 90 and 91 of which areconnected and communicate with the element having the chamber 85. ThisU-shaped element is arranged at the lower end of the chamber and byvirtue of its U-shaped construction provides a space between a wall oflthe chamber 85 and the connecting passage 92 in which space a pluralityof heat exchan e fins 93, 94 and 95 are located. Certain o said fins areconnected with the element having the chamber vthe casing.

85 whereas others thereof such as '100, 101 and 102 are connected to andproject Jfrom the U-shaped member 89. This structure including thechambered element 85 and the Ushaped member 89 is designed to bearranged in a casing 96, the casing and member being disposed relativelyto each other to provide a space 97. Heat radiating lins such as 99, 100and 101 are located in the space 97 provided between the member formingthe passage 92 and the wall 98 of Heat radiatinglins 102, 103 and 104extend from the opposite side o the element providing the passage 92. Itwill be noted that the U-shaped element 89 and these fins are arrangedin the'lower portion of the casing 96 in spaced relation to thelowermost end of the casing and thus air entering the casing at thispoint passes between and contacts with the tubular passage 89 and saidlins is caused to travel upwardly through the casing by convection andescapes from the casing through the opening 105. The casing 96 isprovided with a curved wall 106 which is l:soldered or other- Wisesecured tofthe rear wall 98 of the casing and is provided with a llange107 which produces a water containing chamber 108, the latter. of whichis closed by a removable cover 109. The water contained in the chamber108 will become heated, escape from the chamber and act to humidity theair contained in the room in which the heat exchange device is located.A damper 110 is arranged in the casing 96 and is provided to permit orprevent the low of air through the chamber between the wall 98 and thewall 84 of the heat exchange device.

In all of the embodiments shown, it will be readily apparent that a verylarge area of heating surface is provided for the air, while, at thesame time, there is a of friction to impede the ilow thereof.Furthermore, the air is caused to pick up a relatively large amount ofheat while llowin through a relatively short distance, that is, throughthe channels of the member provided adjacent the base of the variousdisclosed. Due to the expansion thereofthe rate of flow of the air isthus greatly increased, improving the circulation thereof, and hence,its heat exchanging eliiciency. In

` flowing upwardly through the recess it is not permitted tocool-appreciably inasmuch as it is maintained in contactwith thevertical member shown in the various embodiments. The air isthus causedto low out into the room at a relatively high velocity and temperature,Asubstantially none of the heat having been lost before the air entersthe room. Y

Having thus described my. invention, it is obvious that variousimmaterial modications may be made in the samewithout de parting fromthe spirit of my invention;

hence, I do not wish to be understood as limiting myself to the exactform, construction, arrangement, and combination of parts hereinshownand described or uses mentioned. `What I claim as new and di're tosecure by Letters Patent is: Y
